How do i reference / tie notifiers to a device that is within a doofer?

i need to hook up a notifier to a device inside a doofer.
this would be my workaround for naming the control i have.

meaning.

[doofer[*instr.automation]]

the doofer 8 macro knobs can be named → i’ll name them
i’ll automate the doofer 8 macro knobs, they will be auto-bound to the 8 instr automation parameters, which have notifiers routing the content to other places.

what i can’t figure out is … how to get from class AudioDevice - which can let me get to the Doofer, to “inside of Doofer”.
